Boring Bar KA224TM — for VBMT 1604 indexable inserts, 40 mm with internal coolant (A32T)

A Boring Bar KA224TM engineered for precision turning with VBMT 1604 indexable inserts, providing coolant-fed operation and a robust shank for repeatable bore finishes.

• 40 mm diameter for stable cutting
• Internal coolant for efficient chip evacuation
• Compatible with VBMT 1604 indexable inserts
• A32T shank ISO designation, robust construction

Stable cutting and repeatable bore quality

The solid design with a 40 mm body and 32 mm shaft diameter provides the rigidity necessary for consistent internal turning operations. The A32T ISO designation identifies the shank form so that the holder fits common turret and boring bar adapters without modification. With a 300 mm overall length and a mass of 1.79 kg, the tool balances reach and vibration dampening to reduce chatter; the result is fewer reworks and more predictable process windows. These measurable attributes translate directly into higher first-pass yields and lower scrap rates in batch production.

Controlled cooling for longer tool life and process reliability

Equipped with internal coolant, the bar directs cutting fluid precisely to the cutting edge, improving heat evacuation and chip clearance in deep or interrupted bores. Combined with the right-hand cutting orientation and a 107.5° cutting angle, the cooling stream reduces thermal loads on both insert and workpiece, which supports more consistent cutting forces and extended insert life. For operations where cycle time and insert consumption are critical KPIs, this toolholder architecture yields clear efficiency advantages and predictable maintenance intervals.

Secure clamping and straightforward insert handling

Designed for VBMT 1604 indexable inserts, the clamp head accepts standard insert geometry while allowing quick replacement: the clamp width of 22 mm and a cutting height of 50 mm ensure proper seating and stable force transmission. The fastening uses a Torx T15 driver and an M4x10 screw specification for positive torque control and repeatable clamp preload. Indexable inserts offer multiple cutting edges per part, and this system simplifies tool changeover, reducing downtime and supporting lean workflow strategies on the shop floor.

Integration into workshop tooling and logistical benefits

With a 32 mm shank diameter and the A32T mounting standard, the bar integrates with a wide range of adaptors and turret systems, helping to consolidate tooling inventories. The bar’s dimensions (300 mm overall length) and balanced mass enable practical handling and storage, while compatibility with commonly used inserts simplifies procurement and reduces lead times. Supplied under the Teknik Makina label and referenced as KA224TM, the holder is suited to industrial environments seeking standardised, maintainable tooling solutions.

FAQ

What insert type fits this boring bar?
The holder is designed for VBMT 1604 indexable inserts; this compatibility allows use of standard carbide inserts suited to internal turning applications.

Does the bar support coolant-fed machining?
Yes, the boring bar includes internal coolant; the coolant channel supplies fluid directly to the cutting edge for improved cooling and chip control.

What are the mounting and shank details for workshop integration?
The bar uses an A32T shank form with a 32 mm shaft diameter, enabling straightforward mounting in compatible adaptors and turret systems.

How is the insert secured and which fastener is required?
Insert clamping is performed with a screw specified as M4x10, tightened using a Torx T15 driver to ensure repeatable clamp preload.

Is this tool suitable for heavy-duty boring or long overhangs?
The 40 mm body and 32 mm shank provide enhanced rigidity for typical internal turning; the 300 mm overall length offers a balance between reach and stiffness for many shop-floor applications.
